CS Fax does not fax documents directly from Word or PDF formats, because CS Fax would need all the code to draw those documents from their encodings. The PDF viewer for PalmOS just by itself is so big it has a feature to store itself to an external card(!)

However, it is possible to convert basically any document on a PC into a TIF image that CS Fax can handle and then send that to CS Fax via a storage card or even email. Please see the Open Beta Thread for details.
